INFORMATION PROCESSING APPARATUS, SYSTEM, METHOD, AND MEDIUM STORING PROGRAM

摘要

An information processing apparatus may include a memory storing instructions and at least one processor configured to process the instructions to receive an input image. The input image includes either a first image or a provisional image created by iteratively image processing the first image. The instructions further provide for the processor to calculate a local variation of a focused pixel in the input image based on a difference in pixel value between the focused pixel and a surrounding pixel of the focused pixel, to calculate a filter coefficient for suppressing a variation between neighboring pixels in the input image based on the local variation, to create a degraded image by degrading the input image, to calculate a reconfiguration error between the input image and the degraded image, and to create the provisional image based on the filter coefficient and the reconfiguration error.

1. An information processing apparatus for iteratively image processing, comprising:
a memory storing instructions; and at least one processor configured to process the instructions to: receive an input image, wherein the input image comprises either a first image or a provisional image created by iteratively image processing the first image, calculate a local variation of a focused pixel in the input image based on a difference in pixel value between the focused pixel and a surrounding pixel of the focused pixel, calculate a filter coefficient for suppressing a variation between neighboring pixels in the input image based on the local variation, create a degraded image by degrading the input image, calculate a reconfiguration error between the input image and the degraded image, and create the provisional image based on the filter coefficient and the reconfiguration error.
